I have been pondering on this for a couple of days and here is what has come to mind, without analyzing too much. Perhaps the gallows symbols mean the end of something in your life, and combined with the crown it may mean that this ending will have its rewards (the crown of oysters, like bounty from the sea) and will not be a bad thing all-in-all. Hope this helps.
Note: You may want to keep a running diary of images in your meditations and your dreams to see if certain images repeat themselves. Keep it by your bed at night so you can write down the dreams when you get up, as they are still fresh in your mind. These repeating images are usually the most important aspects of your dreams.
A lot of what we see in our meditations and dreams are non-consequential processing of the stuff we go through day-by-day by the subconscious.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
